With so many at-home DNA tests now available to consumers, learning more about your ancestry is easier than ever. Plus, these tests make for thoughtful, unique holiday gifts. All you have to do is ...

At the 8-cell stage of mouse embryo development, the coordination between DNA unwinding and replication appears to improve. © ...

But the replication ‘fork’—the Y-shaped region of an actively replicating genome, where DNA strands are unwound and copied—still moved as slow as did in the 1- and 2-cell stages, creating a mismatch ...

DNA (deoxyribonucleic acid) is the nucleic acid polymer that forms the genetic code for a cell or virus. Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each ...

There are three billion (3,000,000,000) base pairs in the DNA code within each cell. If unwound and tied together, the strands of DNA in one cell would stretch almost six feet but would be only 50 ...

Over the past ten years or so, investigations of degraded or ‘ancient’ DNA have skyrocketed. By extracting DNA fragments from diverse sources —from human teeth and faeces to soil samples and ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...
